# First preliminary step in NEF-workflow. Makes jpg-images quick
# for selection process.

#
# Details of this script:
#
# 1. Makes all filenames lowercase.
# 2. Changes the _ in the D70s-filenames to a chosen number between 0 and 9
# 3. Runs dcraw in cheapest mode for preview-jpg-pictures
# 4. Extracts exif-tags from nef-files and write them to preview-jpg-pictures.
# 5. Remove Orientation-exif-tag as dcraw has already rotated the picture.
#
# Next step of workflow is to run qiv, where the delete-command also
# removes the nef-file.
#
# This script performs its operations on all nef-files present
# in current directory.
